Having it means you cannot write:
SkSize size;
float x, y;
size = {x , y};
clang allows it but GCC does not, claiming it is ambiguous between the
implicitly generated
SkSize& SkSize::operator=(const SkSize&)
and
SkSize& SkSize::operator=(const SkISize&)
clang gives the same error if the former is explicitly declared default.
